Lake effect flurries will affect the regions tonight with a few cm of snow expected in many areas as the flurries will be locally heavy at times.

However conditions will become more favourable for the lake effect snow machine to crank up into a higher gear beginning Wednesday afternoon. Snow squalls may develop giving local snowfall amounts of 15 cm per 12 hours along with local near zero visibility in whiteout conditions from blowing snow and bursts of heavy snow.

Driving conditions will deteriorate by Wednesday afternoon. Local nil visibility and accumulating snow may cause hazardous winter travelling conditions as a result.

Environment Canada is closely monitoring the situation and may issue snow squall warnings as the event draws closer.
